Has anyone ever heard of a 'Stingray' iceboat? I've only recently been introduced to this sport, but I've been doing a lot of web-surfing. A friend has one old busted up 'Stingray' and another in working condition. They were apparently pretty common around here (SE Nebraska) in the late 60's and early 70's. They are basically the same setup as a DN from what I can tell, but I'm guessing about 4' + shorter and 2-seat, simple plywood construction - probably not as high-tech or fast, but a lot of fun. I don't find any reference to it on the web, but would like to find info if it is out there. I think I might try to build one for next season, it looks like something w/in my abilities.
